TTNTT lll SASH-LOCK.

Application filed January 5, 1916.

To all whom it may concern:

Be it known that T, ERNEST MARZINKE, residing at Corona, in the county of RlV6Y- side and State of California, have invented a new and Improved Sash-Lock, of which the following is a specification.

My invention has for its object to provlde a new and improved sash lock for windows of that type in which the windows may be set so as to lock the relatively movable sashes in a more or less open position and it more particularly seeks to provide a sash locking means designed for conveniently and effectively holding the upper sash to a more or less open position for ventilating purposes, and in which the parts are readily so disconnected that the opening and closing of the upper and lower sashes may be effected in the usual manner.

With other objects in view that will hereinafter appear, my invention consists in the peculiar combination and novel arrangement of parts hereinafter explained, specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of my in vention, so much of a window casing and the upper and lower sashes being shown, necessary for illustrating a practical application of my said invention. Fig. 2 is a vertical section of the meeting ends of the upper and lower sashes with my invention applied, the upper sash being shown at a partly lowered or ventilating position. Fig. 3 is a horizontal section thereof taken substantially on the line 3--3 on Fig. l, the upper sash being at the uppermost or closed position, and the manner of removing the loosely mounted locking member indicated in dotted lines. Fig. 4: is a perspective view of the ratchet member that is secured to the lower end of the upper sash. Fig. 5 is a detail perspective .view of the parts that constitute the locking member, hereinafter specifically referred to. Fig. 6 is a vertical section of the upper corner of the lower sash and the adjacent portion of the window casing or stile, the movable locking member being shown in a locked engagement with the casing. Fig. 7 is a plan view of the sheet metal blank of which the bottom section of the locking member is formed. Fig. 8 is a similar view of the metal blank from which the upper section of the said locking member is formed.

While my invention may be readily applied to windows having no sash weights, it is more especially designed for connec' tion with weighted sashes and for holding the upper sash locked when lowered for ventilating purposes only.

In the drawings the upper and lower sashes 1-2 as shown are guided in the usual runways 3.

4 designates a locking rack plate that is attached to the lower left hand corner of the upper sash, see Fig. 1, and the said plate has a vertical series of equi-spaced openings 5, between shoulders or looking abutments 50, in alinement with a vertical groove 51 in the front face of the rack plate and which extends the full length of the row of openings 5 as is best shown in Fig. 4, by reference to which it will also be seen the lower end of the groove 51 merges with a laterally extended groove or cut out portion 42 in alinement with the lowermost one of the openings 5, the inner edge 55 of which is beveled, the reason for which will hereinafter appear.

6 designates a locking bolt formed with the usual beveled head and the said bolt is mounted in a two part casing, preferably of heavy sheet metal, the construction of which is best shown in Fig. 5, by reference to which it will be seen the bottom section of the bolt casing includes a base member 7 having bent up flanges -71 at the opposite edges and an intermediate bent up flange 72, the latter and the flange 71 forming the bearings for the spring bolt 6. The base member 7 also includes a slotted extension or tongue 73 at one end and a finger pull portion 74: at the other end.

The upper casing section includes a top 8 and downwardly bent side flanges 80-81, one of which 80 has an aperture 82 to receive the bolt head. Flanges 80 and 81, when the two parts of the casing are assem bled, lap over the vertical flanges 7 0-71 of the bottom casing section, see Fig. 2, and the flange 80 includes a pendent extension 80 that laps over the outer face of the upper end of the lower sash when the locking member is applied for use and as clearly shown in Fig. 2. The upper casing section also includes a downwardly bent flange 84: at one end thereof, a horizontal extension 85 and a cut out portion 85 at the other end, the extension 85 having a slot 86 that registers with the slot 7 3 in the tongue portion 'of the lower casing section, when the casing parts are assembled as shown, said sections, in practice, being secured by screws or rivets 7 5.

In applying my sash lock for use, the up per sash is first pulled down until the upper end of the plate passes below the upper edge of the lower sash. The locking member having the latch bolt is then placed upon the upper left hand corner of the lower sash with its out out portion 85, engaging the parting bead Z, see Fig. 1, and with its slotted tongue 73 inserted in a horizontal slot X in the casing, see Figs. 3 and 6, and with its pendent flange 80 lapped over the inner face of the said sash, it being understood that the registering slots in the tongue 73 and the extension 85 provides for the free play of the sash cord. After the said looking member is positioned as stated, the upper sash can be raised to a partial or wholly closed position, since the latch or lock bolt will now readily slip into successive engagement with the rack openings 5 and thereby lock the said upper sash from being pulled down. WVhen the upper sash is pushed to its uppermost or closed position, the latch bolt 6 will be in the bottom or last ratchet opening 5 and when in such position the said locking member can be readily removed from engagement with the ratchet member and the lower sash, by pulling it back in the direction of the arrow and as indicated by dotted lines on Fig. 3, such operation being provided for by beveling that edge 62 of the latch bolt 6 that engages the beveled edge 55 of the lowermost opening 5, to thereby cause the bolt to recede against the tension of its spring 63, as shown.

From the foregoing description taken in connection with the drawings the complete construction, the maimer of operation and the advantages of my invention will be readily apparent.

By reason of removably mounting the locking memberon the lower sash and causing it to engage with the pulley stile as stated, the lower sash is held from being moved upward and the upper sash is held at any point within the limit of its ventilation adjustment and securely locked in place, and by reason of the locking member being readily removed in the manner stated, when said member is removed, the two sashes may be raised or lowered in the ordinary manner to their full extent.

What I claim is:

1. The combination with the upper and lower sashes and the window frame; of a sash holding device comprising a latch member adapted to be located on one sash, a lock rack secured to the other sash, said latch member having means for engaging the window frame for holding one sash in a fixed position while the other sash moves to effect different engagements between the latch member and the lock rack, said lock rack having provision whereby the said latch member may be disconnected therefrom when the sash carrying the rack is in a predetermined position.

2. The combination with the upper and lower sashes and the window frame, the latter having a horizontal recess in 1111c with the top of the lower sash when at the closed position, and a rack member having a series of vertical rack openings; of a latch member adapted for being seated on top of the lower sash and having a tongue-like extension adapted for entering the horizontal so recess in the window frame, said device including a spring bolt adapted for successively interlocking with the rack openings as the upper sash is moved upwardly and the lower sash is held down, said rack having provision whereby the said latch member may be disconnected from the rack and moved laterally with respect to the rack when the upper sash is at its uppermost or closed position to permit of the said latch device being removed from the lower sash. 3. The combination with the upper and lower sashes and thewindow frame, the latter having a horizontal recess in line with the top of the lower sash when at the closed position, and a rack member having a series of vertical rack openings; of a latch member adapted for being seated on top of the lower sash and having a tongue-like extension adapted for entering the horizontal 1 recess in the window frame, said device including a spring bolt adapted for successively interlocking with the rack openings as the upper sash is moved upwardly and the lower sash is held down, said rack having provision whereby the said latch member may be disconnected from the rack and moved laterally with respect to the rack when the upper sash is at its uppermost or closed position to permit of the said latch device being removed from the lower sash, said rack device having a guide groove on its front face in alinement with the vertical series of ratchet openings and a lateral guide groove that extends across the rack member in alinement with the lowermost one of the rack openings, said lowermost opening having a beveled edge at the lateral guide groove side, the latch bolt having a beveled bead portion for engaging the said beveled edge of the said lowermost opening for the purposes stated.

4:. The combination with the upper and lower sashes and the window frame having a horizontal recess; of a sash holding device that comprises a rack plate secured on the lower front edge of the upper sash and a latch device removably mountable on the top of the lower sash and including a spring latch belt for engaging the rack plate when the upper sash is raised, said latch device comprising a lower section having bent up side flanges and an intermediate bent up flange, the aforesaid spring rack bolt being journaled on one of the side flanges and the intermediate flange, said lower section including a slotted tongue for entering the recess in the window frame, an upper section that includes side flanges adapted for lapping over the side flanges of the lower sec tion, and a shouldered extension having a slot that registers with the slot in the tongue portion of the lower section.

5. The combination with the upper and lower sashes and the window frame, said frame having a recess at the meeting line of the upper and lower sashes, and a rack member mounted on the lower end of the front face of the upper sash; of a locking device adapted to be loosely held on the top of the lower sash, the said device including a spring bolt for riding over and interlocking with the rack member, the said device having lateral movement on the lower sash and a locking member adapted to be pushed into the aforesaid recess in the window frame, the said rack having provision whereby the spring bolt may be moved out of engagement with the rack as the locking device is moved laterally on the lower sash in a direction away from the window casing and to thereby release the locking member from the recess in the window frame.
